4Patenteiad ept. 8, 1931l UNITED STATES PATENT OFFICE CLARENCE M.CLARKE, OF SYRACUSE, NEW YORK, ASSIGNOR TO UNITED. STATES HOFF- i MANMACHINERY CORPORATION, .0F NEW YORK, N. Y., A COR-POIRATION 0E DELA-WARE GARMENT PRESS Application led March 26, 19291 'Serial No. 350,089.`

This invention relates to garment presses and particularly to togglemechanisms for actuating the same.

The prime purpose of the invention is to provide a commerciallypracticable linkage, capable of exerting great force and. offering awide opening movement of the press and compact arrangement. j

The linkage comprises two thrust links combined with a floating memberto which the links are pivoted at spaced points, so that the ioatingmember may be brought into thrust alignment with the .links by a .com-

pound swinging and rotating movement ofranging the parts may be made toform a.

secondary toggle with the'movable member, and thus enhance the forcemultiplying func tion of the irst toggle;

Various structures for supporting the buck, and guiding the movable headrela-v tively thereto are known, and the linkage her in disclosed isgenerally applicable, but will be described as applied to a conventional t pe of press in'which `ythe head is carried y a verticallyswinginglever.`

is a section on the linea-1 ofgenerally by thenuf` 17. The upper maintoggle link is longitu.

dinally compressible and is adjustable-as to length, this being a knownconstruction. 'It includes a head 18 j ournaled in the trunnions19,1i`xed in yoke 12 by the set'screws 21;

a thrust. rod 22 swiveled in the head 18 and rotatable by a hand wheel23; a thrust collar 24 pinnedto rod 22; a spring seat 25' into which rod22 is threaded; a guide stem 26 fixedr in spring seat 25; a combinedspring seat-and forked fulcrum block 27 yguided on said stem and acompression spring 28 s1.; rrounding' said stem` and reaching between.said spring seats.

The lower end ofgthe-upper main toggle link (part 27) vis hingedbyjournal pin 29 andthe upper end of the lower main toggle link 17 ishinged by journal pin 31, to a.

floating-thrust member 32 having an .arm 33. The pins 29 and 31 arespaced-apart in this`^ member a substantial distance and the arm 33extends in a direction generally transverse to the line connecting thecentersl of the journalpins. Near itsf end the arm 33 carries a journalpin 34;

A lever 35 is pivoted between its ends at 36 to the frame \6. One end ispivoted to the pin. 34, the other end is connected by a ten- `sionlinkl37 (shown as adjustable in length) to a foot lever 38 which isjournaled on pin 16- at the rear of the machine 'and terminates 'at thefront of the machine in a foot pedal 39.

- f The fulcrum points on the-frame fare so located and the moving partsare so formed d dimensioned, that at the -limit of downard motion oflever 38, the journalpins- 16, 3-1 and 29 and the'trunnions 19 lie-in astraight. line or substantially so (full Vline position,"Figure l) andlever 35 aligns with arm 33. Thuswthe press locks closed in a familiarmanner.

The foot lever 38 may .be raised sufficiently to break the' toggle strutaction by. means of a kick-off pedal 41 pivoted'in the frame 6 at 42 andhaving a rearward extension 43 which underlies lever 38. The pressopening movement of the linkage is arrested by collision of narm 33 withbuffer 44 on lever 38 (see y, dotted line position, Figure l).

Various changes may be made in the specitic details of the linkage, andas stated it is generally applicable to garment and like presses ofvarious known types.

What is claimed is:

l. In a press, the combination of a fixed frame; a fixed pressingelement supported thereby; a second pressing elementl cooperativetherewith; a pivoted supporting memher for said second pressing element;a link pivotally connected at one end to the pivoted supporting member;a link pivotally supported on the fixed frame; a thrust member havingspaced pivotal connections with the links and having a third pivotdisplaced from 5the line connecting its pivot connections with the twolinks, the four pivotal connections of the two links being substantiallyaligned when the press is closed; and

means for moving the third pivot of the thrust member in a definite pathto cause said four pivotal connections lof the links to move toward andaway from alignment.

2. In a press, the combination of a fixed frame; alfixed pressingelement mounted thereon; a second pressing element cooperativetherewith; a pivoted support for said second pressing element; a linkpivotally supported on the fixed frame; a link pivotally connected tothepivotal support for the second pressing element; a thrust member havingspaced pivotal connections` with the links, and having a third pivotdisplaced `from the line connecting its pivot connecmember guided onsaid frame to move in a definite path; a head carried by said memberinto and out of pressing relation with said buck; a pair of links, onepivoted at one end to said fixed frame and the other pivoted at one endto said movable member; a thrust member pivot-ed at spaced points to theother ends of said links and having an arm extending laterallyrelatively to a line connecting said spaced points, and having a thirdpivot; a lever pivoted to the fixed frameand to said pivot; and meansforv swinging said lever, the parts being so dimensioned and the pivotconnections being so located that the lever and said arm swing intosubstantial alignment as the four pivot points of the first two linksapproach substantial alignment.

In testimony whereof l have signed my name to this specification.
